upgrading Gnome to the Ximian Desktop fixes the problem with the "pipes" screensaver, but doesn't affect the problem with the "atlantis" screensaver. The problem with the "atlantis" screensaver is critical since it hangs my desktop and cannot be corrected by killing X or gdm.
This is almost certainly an issue with the XFree86 drivers, or possibly the kernel DRM drivers.
Disable DRI in your X config, and report back if the problem goes away.
Disabled the DRI modules and it corrected the problem.
This problem is believed to be fixed now, and affected pretty much all DRI enabled drivers. Please test the latest rawhide X and kernel either using the Red Hat Linux (Null) beta, or once the new release of Red Hat Linux is completed and released. After testing this out with our latest kernel/X, please provide updated status, and if the problem persists, please attach your X server log and config file. Please test this out with DRI enabled to see if it works properly with the latest package releases.
Assuming problem is fixed in current kernel update as described above due to lack of response. Closing as ERRATA.
